<![CDATA[The mathematical literacy of elementary school students in Indonesia is still relatively low, as reflected in the results of the 2022 PISA survey which showed that the average score of Indonesian students was below the OECD average. One of the causes is the lack of contextual and interesting teaching materials, such as Student Worksheets (LKPD) that integrate local culture. This study aims to develop LKPD based on ethnomathematics with the context of Javanese batik motifs to improve students' mathematical literacy in the material of folding symmetry and rotational symmetry. This study uses the Research and Development (R&D) method with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The subjects of the study were grade V students of SDN 106830 Sidodadi Ramunia. Data were collected through observation, interviews, expert validation questionnaires, mathematical literacy tests, and student response questionnaires. The results of expert validation showed that the LKPD developed was very feasible to use with an average score of 100%. Field trials showed an increase in students' mathematical literacy with an N-Gain value of 0.58 (moderate category) and classical completeness reaching 82.35%. Students' responses to LKPD were also very positive with a percentage of 93%. The conclusion of this study is that the LKPD based on Javanese batik ethnomathematics developed is feasible to use and effective in improving elementary school students' mathematical literacy. Suggestions for further research are to expand the scope of integrated local culture and develop LKPD in digital form to increase the appeal of learning.]]>
